If this stop were not provided, the operator niigl t carelessly force brick inwardly so far that it would receive a crushing blow from an approaching cutter or cutters. The radial arrangement of the upper surface of the shelf relatively to the axis of the head, causes each row of cutters to approach-and cross the shelf with its axis substantially parallel with the shelf, so that the cutters roll easily across the inner face of a brick without scraping and without being pressed sidewise against the walls of theslots in the head. The rolling contact of the cutters with the material on which they act reduces to the minimum the wear of the cutter teeth, there being no such wear as would be caused by a scraping movement of the teeth in contact with the material. The absence of side Wise pressure of the acting cutters on the walls of the slots, reduces to the minimum not only the frictional resistance to the rotation of the cutters (so that their teeth have no tendency to scrape) but also the power required to rotate the head.

I prefer to make each cutter by stampln it from a relatively thin sheet of steel, an to provide two cutters for each slot, although, if desired, the thickness of each cutter may be sufiicient to substantially fill its slot, as indicated by Fig. 5.

The shelf 22 may be adjustable toward and from the outer face of the head 16, and as here shown, the shelf is provided with an arm 23 having a slot 24 through which passes an attaching bolt 25, the slot and bolt permitting the described adjustment of the shelf.

26 represents a hood which partially 1ncloses the head 16 and communicates with a fan casing 27 in which is located a rotary suction fan 28 mounted on a shaft 29 which is journaled in bearings 30 on the frame 12. The rotation of the fan 28 draws a current of air through the hood 26, the air carrying the dust raised by the cutters and discharging it through a flue 31 communicating with the fan casing.

The shafts 14 and 29 are preferably rotated in unison by a suitable motor 32 mounted on the frame, the shaft of the motor being provided with a driving pulley 33, connected by a belt 34 with a pul ey 35 on the shaft 14..- A pulley 36 on the shaft 14 is connected by a belt 37 with a pulley 38 on the shaft 29. It is obvious that any other suitable driving connection ma be provided between the motor and the lead 16 and fan 28.

The machine may-be provided with two heads 16, located at opposite ends of the toward the face, and. a brickshaft 14', the shelf 22, hood 26 and suction 'an 28 being dupl I claim l. A brick cleaning machine comprising icated, as shown by Fig. 2.

a rotary head having an outer face ar-' head, studs attached to the head behind said face, each stud extending across a'row of slots, rows of serrated cutters mounted to rotate loosely on said studs and projecting into said slots, some of the teeth of each cutter projecting outwardly from said face to have a rolling engagement with an accumulation of mortar on abrick pressed supporting shelf adjacent to the head, the portions of the outer face of the head between the slots serving as a stop to limit the movement of a brick into the spaces between the axes of the cutters.

2. A brick cleaning machine comprising a rotary head having an outer face an ranged in a plane substantially at right angles to the axis of the head, and numerous spaced slots arranged in substantially radial. rows, all the slots being separated from each other by intervening portions of said head, studs attached to the head behind said face, each stud extending across a row of slots, rotate loosely on said studs and projectin into said slots, some of the teeth of each cutter projecting outwardly from said face to have a rolling engagement with an accumulation of mortar on a brick pressed toward the face, the portions of the outer face of the head between the slots servin as a stop to limit the movement of a brick lnto the spaces between the axes of the cutters,

rows of serrated cutters mounted to and a fixed brick-supporting shelf adjacent to said outer face and having a supporting surface arranged substantially radial to the axis of the head whereby the cutters of each row approaching the shelf are caused to roll across the inner face of a brick supported thereby with the minimum of frictional resistance and wear, the cutters of each row being staggered relatively to the cutters of the adjacent rows.

' A brick cleaning machine com rising a rotary head having a face substantially at right angles with its axis of rotation, said head having slots arranged in radial rows,

and a corresponding series of radially arranged studs removably attached to the head behind the series of slots and extending across the slots, and ated circular cutters mounted to rotate lo y on said projecting through the slots, thi
